CS1600

Low-cost PFC Controller for Electronic Ballasts

Features & Description

 Lowest PFC System Cost for Electronic Ballasts

Description

CS1600 is a high-performance Variable Frequency Discontinu-

ous Conduction Mode (VF - DCM), active Power Factor

Correction (PFC) controller, optimized to deliver the lowest PFC

system cost for electronic ballast applications.

 Variable Frequency Discontinuous Conduction Mode

 Improved Efficiency Due to Variable Switching Frequency

 EMI Signature Reduction from Digital Noise Shaping

 Integrated Feedback Compensation

A variable ON time / variable frequency algorithm is used to

achieve near unity power factor. This algorithm spreads the EMI

frequency spectrum, which reduces the conducted EMI filtering

requirements. The feedback loop is closed through an integrated

compensation network within the IC, eliminating the need for

additional external components. Protection features such as

overvoltage, overcurrent, overpower, open- and short-circuit pro-

tection, overtemperature, and brownout help protect the device

during abnormal transient conditions.

 Overvoltage Protection with Hysteresis

 Overpower Protection with Shutdown

 UVLO with Wide Hysteresis

 Thermal Shutdown with Hysteresis
